Product details
Overview
IR38060MGM12TRP from Infineon Technologies is a digitally configurable, synchronous buck DC-DC converter with integrated MOSFETs and PMBus interface, delivering up to 6 A at 1.2 V output. It operates from a single 5.5–16 V input, features 0.5% reference voltage accuracy, supports 607 kHz fixed switching frequency (pre-configured), and includes true differential remote sensing for precision load regulation in server point-of-load applications.
For engineers reviewing the IR38060MGM12TRP datasheet, IR38060MGM12TRP pinout, IR38060MGM12TRP application, or IR38060MGM12TRP equivalent, key selection criteria include its pre-programmed 1.2 V output, thermally compensated current limit, dedicated output voltage sensing protection active during disable, and dual-mode operation (analog fallback without PMBus).
Technical Context
The IR38060 implements a voltage-mode PWM controller with internal LDO biasing (VCC = 4.5–5.5 V), enabling single-supply operation from PVIN. Its control loop uses an error amplifier (COMP) with external compensation and supports both analog (Rt/SYNC resistor-set) and digital (PMBus) frequency configuration up to 1.5 MHz.
It integrates high-side (14–27 mΩ RDS(on)) and low-side (6–12 mΩ) MOSFETs, a bootstrap diode, and a remote sense amplifier (RS+, RS−, RSO) with ±0.5% output voltage accuracy over temperature. Fault management includes programmable overcurrent response, OVP/UVP on Vsns, and junction temperature monitoring via TMON.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V - pre-configured at factory; eliminates external resistor divider and reduces BOM count. |
| Max Output Current | 6 A continuous - supported by integrated MOSFETs with thermal derating above 85°C ambient. |
| Switching Frequency | 607 kHz - fixed, optimized for efficiency/size trade-off; enables use of compact 0.47 µH inductors. |
| Reference Accuracy | ±0.75% (0.75–1.25 V FB range) - ensures tight output regulation under load transients and temperature drift. |
| Input Voltage Range | 5.5–16 V - enabled by internal LDO; allows direct connection to 12 V rail without auxiliary bias supply. |
| Junction Temp Range | –40°C to +125°C - validated for industrial and server environments; thermal shutdown activates at 150°C. |
| PMBus Commands | 66 commands - support real-time telemetry (IOUT, VOUT, TMON), fault logging, and dynamic margining. |
Pinout & Package
IR38060MGM12TRP is housed in a thermally enhanced 5 mm × 6 mm PQFN package with exposed thermal pad (PGND-connected). The 26-pin layout supports high-current paths (dual PGND pins), differential remote sensing, and dual-mode communication (PMBus/analog).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1) | Main power input | Accepts 5.5–16 V; requires local 22 µF ×4 + 0.1 µF ceramic bypassing to adjacent PGND pins. |
| BOOT (2) | High-side gate driver supply | Connects via 0.1 µF capacitor to SW; series 0 Ω (or 1 Ω if PVIN >12 V) enables robust boot charging. |
| VSNS (5) | OVP and PGood sense input | Dedicated overvoltage detection path; remains active even when EN is low - critical for system safety. |
| FB (6) | Error amplifier inverting input | Direct connection to output or remote sense net; sets regulation point - unused in pre-configured 1.2 V variant. |
| RT/SYNC (14) | Frequency control / sync input | Floating in digital mode; in analog mode, sets fSW via resistor to GND (607 kHz ≈ 3.83 kΩ). |
| EN/FCCM (15) | Enable / forced CCM mode | Pull >1.2 V to enable; <3.1 V forces continuous conduction mode - improves light-load stability. |
| SCL/OCSet (19) | PMBus clock / analog OCP threshold | In analog mode, 4.7 kΩ pull-down sets overcurrent trip; in digital mode, standard SMBus clock line. |
| SDA/IMON (18) | PMBus data / analog current monitor | Provides voltage proportional to IOUT (0–2 V full scale) when PMBus inactive - enables analog telemetry. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | Monolithic 6 A buck stage with matched top/bottom MOSFETs (RDS(on) ≤27/12 mΩ) eliminates external FETs and gate drivers. |
| True Differential Remote Sensing | RS+, RS−, and RSO pins enable millivolt-level load regulation accuracy despite PCB IR drop - essential for CPU/GPU rails. |
| Dual-Mode Operation | Operates as fully digital PMBus device or standalone analog regulator - no firmware required for basic functionality. |
| Pre-Bias Start-up | Soft-start circuit safely ramps output from pre-biased loads (e.g., hot-swap systems) without reverse current flow. |
| Dedicated Output Protection | VSNS-based OVP remains active during shutdown - prevents damage from upstream rail faults or sequencing errors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
Does IR38060MGM12TRP require external programming to operate at 1.2 V?
No. IR38060MGM12TRP is factory pre-configured for 1.2 V output and 607 kHz switching frequency. It functions immediately upon power-up with EN pulled high, requiring no PMBus initialization or external resistor dividers. The FB pin is internally tied to achieve the target voltage.
Can IR38060MGM12TRP be used without a PMBus host controller?
Yes. In analog mode, it operates as a standard buck regulator: SCL/OCSet and SDA/IMON provide analog OCP threshold and current-proportional voltage output, while SALERT/TMON delivers junction temperature voltage. No digital interface is required for basic regulation.
What is the purpose of the TRACK_EN pin in this pre-configured variant?
TRACK_EN enables voltage tracking for power sequencing. When pulled low, it synchronizes IR38060MGM12TRP's soft-start with another regulator's output (via VP pin). For standalone use, connect to P1V8 through a 100 kΩ resistor to disable tracking and ensure proper startup behavior.
How does the dedicated VSNS pin improve system reliability compared to standard FB sensing?
VSNS provides independent overvoltage protection that remains active even when EN is low or the IC is disabled. This prevents catastrophic damage from upstream rail faults or external feedback loop failures - a safety-critical feature absent in conventional FB-based OVP schemes.
